Document Summary
International association for the society of pain (iasp) describes pain as an. Unpleasant sensory and emotional experience that is associated with potential or actual tissue damage . Pain is whatever the experiencing person says it is, existing whenever he says it does. Subtle issues of definition have significant and clinical implications. The ability to locate painful stimuli and describe the intensity and quality is referred to the sensory-discriminable aspect of pain. The sensations are controlled through the afferent nerve fibres, spinal cord, brainstem and higher brain centre which results in prompt withdrawal from painful stimuli. The unpleasantness of experiencing pain produces an emotional response which produces changes in both mental state (affect) and behaviour (motivation) Referred to as the affective-motivational aspect of pain. The degree of response depends on the intensity and duration of the pain, past experience and treatment option/availability. The intensity of the pain experience can be modified by behaviour, cognitive and clinical interventions.
